地下连续墙铣槽法在地铁托换保护结构中的应用

The Application of the Trench Cutting Mothed of Diaphragm Wall in the Subway Underpinning Structure

铣槽机作为一种较先进的地下连续墙施工专用设备,施工精度高、施工震动小,且适用于高强度岩层,对周边环境影响小,因此较多地用于对施工环境有特殊要求的地下连续墙工程。本文以广州泰康路某商业楼地下室工程为例,介绍了铣槽机在地铁托换保护结构工程中的应用,取得了良好的应用效果。

Trench cutting machine is a kind of advanced equipment for the construction of diaphragm wall,construction with high precision and small vibration,suitable for high strength rock,and with little impact on the surrounding environment,so the machine was used for the construction of diaphragm wall with special requirements on environment. In this paper,the subway underpinning structure under the basement of a commercial building on the Taikang road in Guangzhou,a method of diaphragm wall construction with trench cutting machine is introduced, bring excellent effects in practice.
